"Uhm...Excuse me Mr. Kel'Thuzad, but where is this aura coming from?"
Kel'Thuzad turns his head and saw a pink pony, like Pinkie Pie, but with no fluffy hair and has wings.
"I will not tell you until you tell your name."
"My name is Princess Cadence, for your information."
"Ah, I see. Your the ex-foalsitter the young one spoke of."
"Yes, now give us that information, or my guards will hunt you when you escape."
"Certainly. The aura is coming from that direction." he said, pointing at the throne room. He moved to the throne room, with the ponies following him. He stopped in front of the throne, with ponies wondering what will he do next. Then, he raises his hands, with purple glows emitted on them, and casting that most believe was a spell. Twilight would not imagine a being like him would do magic. Minutes later, the throne split in half, revealing a chamber. The ponies would have never thought of that before, not even Twilight Sparkle or Princess Cadence. Kel'Thuzad went inside the chamber, with a mob of curious mares following.
"This chamber, if I may talk Princess, leads to the aura that I was sensing. It is powerful, almost like it was here and not touched for a thousand years." Kel'Thuzad said.
"That powerful?" Twilight asked.
"Yes, but I think more powerful that we could ever imagined."
But before Twilight could reply to Kel'Thuzad, he stopped in front of something. The ponies watch at Kel'Thuzad approach the crystal wall. He realized that there was something behind it, and when he wipe some of the fog, a pony face appeared, with stripes in it's body. Wanting to meet this pony, Kel'Thuzad again uses a spell, with Twilight wondering. He said:
"Let this power shatter the crystal, and release the body from within!"
In a second, the crystal wall and comes forth a pony. He was unconcious and Kel'Thuzad tries to wonder why a pony, trapped in a crystal wall, was here.
